Widget usage examples

[jonathandlynch at gmail.com]

Hi Herman,

To get the base64encoded data to work for an image in the browser widget, don't forget the following line in LC:

Replace linefeed with empty in tBase64data


When you export an image to a variable and then base64encode the variable, LC adds in extra linefeeds. They have to be removed to work in the browser widget.

Does that help?
